TOOL FOR FINISHING THE EDGES OF BOOTS AND SHOES.

SPECIFICATION forming` part of Letters Patent No. 236,145, dated January4, 1881.

Application filed July 24, 1880.

1'0 all 'whom tt 'may oo'ncern -Be it known that I, SAMUEL N. OORTHELL,of the town of Quincy, State of Massachusetts, have inventedImprovements in Tools for Finishing Ithe Edges of Boots andShoes, ofwhich theV following is a specification.

I`his invention relates to improvements in tools for finishin g theedges of boots and shoes;

I and the invention will, in connection with the annexed drawings, beherein fully described, and specifi cally detined in the appendedclaims.

Figure 1 is a side elevation of a machine having my improved toolsthereto applied. Fig. 2 is a detached reverse view, showing therand-tool and gages as applied to the machine. Fig. 3 is a sideelevation of the randcutter as viewed from the right in Fig. 1 and leftin Fig. 2. Fig. 4 is a detached elevation of the Vertical rand-gage asviewcd from the zo left in Fig. land right in Fig. 2. Fig. 5 is a top orplan view ofv said gage. Fig. 6 is an under-side or inverted-plan viewof the horizontal rand-gage. Fig. 7 is a 'detached elevation, showingthe edge-trimmer disk-gage as viewed from the left in Fig. 1, said diskbeing in part broken away to show the cutter behind it, the Verticalgage being also shown in elevation. Fig. 8 is a detached view showing,in partial (liame'tric section, taken through one of its teeth, theedge-cutter and its diskgage. Fig. 9 is a detached longitudinal sectiontaken through the rand-cntter, and showing its shaft transversely takenaway. Fig. 10 .is a top or plan view of my Vertical edgecutter gage.Fig. 11 is a detached Vertical section, showing a shoe-sole edge as itleaves the pegging-machine and before commencing the finish of the edge.Fig. 12 is a section similar to Fig. 11, but showing the sole-edge asoperated upon by the rotary rand-cutter,

which latter and its gages are shown in position by dotted lines. Fig.13 is a section similar to Figs. 11 and 12, but showing the soleedge ascompleted by my improved cutter,

which latter is shown in position by dotted lines. Fig. 14 is alsoa-section similar to the preceding, but intended for illustration inshowing the result of the previous methods and tools used for a similarpurpose.

In these views, A represents a frame, which may be of such form and sizeas will best (No model.)

adapt it to,the conditions and place where it is to be used.

B is an arbor journaled in boxes at the top of the frame, as shown.

O is a pulley secured on arbor B, to receive the belt by which rotarymotion is imparted to said arbor and the tools thereon mounted.

At the opposite or left-hand end, Fig. 1, the usual shank-trimming toolais mounted. This tool oonstitutes no part of my invention. ln saidshaft, nearer the journal bearings, is mounted the cutter b andrand-disks o, which are secured thereon between the fixed collar d andthe screw-nut e in the usual manner.-

The cutter b is of well-known form and construction, except the narrowgroove f, which is cutin its teeth at the intersection of lines g and h,as is plainly shown in the enlarged Fig. 8. The object and office ofvsaid groove f will be hereinat'ter specitled. i The disk c is formedwith the holes i, which are so arranged therein that when mounted withcutter I) onl arbor B they are just within the circumferential linedescribed by the lines g of the teeth of the cutter, and are coincidentwith the open spaces between said teeth, as shown in Fig. 7. i

In Figs. 1, 7, and 10 a gage-support, j, is shown, which is secured inposition by the vcap-screws of the jonrnal-bearin g of the frame,

or it may be secured to the frame in any desired manner. At the outerend of this sup- .port two curved arcs or fingers, lc lc, are' securedby the screw l, which passes through the slots m m, Fig. 10, in saidares, whei'eby vthesame may be so adjusted as to leave a greater or lessspace between the lower ends 'of said arcs, in order to allow the teethof cuttel'l b to extend below the same to the required go extent in vthefinishing of different kinds of boots or shoes.

An arbor, D, is journaled below arborB in -projecting sleeve F of frameA, or its equivaplan in Fig. 3, and it is of slightly less diameter thanthe gage-disk o.

A gage-holder, p, is seoured to sleeve F by the screws s, as shown, andso as to be vibrated thereon, in order that the end next to cutter n,and in which stem u' of gage t is secured by setserew n, may be raisedor lowered, as required. The form of said gage tand its relation toarbor D are shown in Fig. 4, and said gage may, by means of set-screw o,be adjusted at the desired distance from arbor I). It may also, by thedescribed vibration of holder 1), be arranged oblique or paralleltheretO.

A gage, w,whose face is oblique to the axis of arbor D, ishorizontallyadjustable relatively to eutter n, and it is secured tosleeve F by screwi ,which passes through the slot in stock x, Fig. 6,such stock being held from rotationv on said screw by steady-pins 011either side thereof, as shown by dotted lines in Fig. 1.

The operation of said tools is as follows: After the sole 1 and upper 2of the shoe have been united, as shown in Fig. ll, the next operation isto cut the bevel termed the rand?7 (Shown at 3 in Figs. 12, 13, and 14.)Heretofore this has been done by employing disks 0 as a guide, which,being inserted and traveling in the converging space between the soleand upper, thereby operated as a guide; but I adjust the vertical gaget, against which the sole-edge bears, at the desired distance from theperiphery of eutter a to allow said cutter to cut the rand to therequired distance from the edge of the sole or width of the surfacethereof. I also adjust the gage w at such distance from the face ofcutter n that the thickest soles of a lot or case of boots or shoes(intended to be of uniform thickness at the edge) will pass between suchedge and eutter, while, by varyiug the position or angle of the plane ofthe thinner soles relatively to the eutter, the desired width of randmay be cut therein without moving gage w; or, in other words, when disko served as the guide or gage the rand was cut relatively to the top ofthe sole, while, by the use of gage w, such rand is now cut relativelyto the bottom of the sole. In Fig. 7 the position of the shoe sole andupper when the rand is being` cut is shown by dotted lines. After therand has` been cut' by rotary eutter n in the manner described, leavingthe sole in the condition shown in Fig. 12, the shoe is then'sub-]'eeted to the action of cutter bon shaft B, the shoe being held in thehands of the operator, as when cutting the rand, beneath the cutter, andwith the edge of the sole resting upon the arc-like fingers lc k, asshown by dotted lines in Fig. 7. As the edge is moved past said eutterthe inner face of the perforated disk c acts upon the rand and smoothsthe same by the action thereon of the angles at the oriiices of holes z'in said disk, while the edgeet of the sole is cut by the line q of cutter d, and the grooves fin said eutter forms and finishes the corner 5,as shown in Fig. 13. Without such groove the corners of the sole will beslightlyrounded, instead of presenting the full appearance which saidgroove causes, and which is regarded as the best style of a tinishededge.

In Fig. 14 the lower corner of the sole is shown at 6 with a bevel orshort face cut by line h ot' eutter Z), which would result in case of asole thicker than those for which eutter b was adapted if the rand wascut with disk 0 serving as the guide or gage, instead of gaging from thebottom of the sole with gage w, as described.

I am aware that heretofore inventions have been patented for the samepurpose, wherein were embodicd gages by which to adjust the shoe-soleedge relatively to the cutters, and that the rand guides or gages soemployed have been perforated as described, and I make no claim to suchperforated rand-guides, or, broadly, to the cutters or gages or partstherewith employed, my invention being contined to the subject-matterdefined, set forth, and einbraced in the several claims which areappended to or constitute the termination and summing up of thespecification, wherein I have set out and described my invention inconnection with such other unclaimed parts as were necessary for theproper elucidation of the functions of the said specific devices, which,as above stated, constitute the precise features or substance of myinvention, which I hereby seek to protect by Letters Patent.

The gage w may be adjustably pivoted to its stock x by the pivot 7 inFig. 1.

I claim as my invention- 1. In the rotary eutter b, the circumferentia-lgroovef, formed in the teeth thereof, at the intersection of lines r/lt, whereby a full finish is imparted to the sole at the angle thereof,substantially as specified.

2. In combination with the rotary edgecutter I), the gage kk, to controlthe depth of cut upon the sole-edge, substantially as specilied.

3. In combination with rand-eutter n, the gage w, pivoted to theholding-stock x, and the latter slotted to receive the holding-screw y,whereby said gage may he adjust'ed in its distance from the cutter,andmay be vibrated upon its pivot to the desired obliquity, substantiallyas specified.

4. The combination of arbor D,With itsrandeutter n and gage-disk 0, withthe gages tand w, and arbor B with its eutter b and gage-disk c, allsubstantially as and for the purposes specified.
